Plastic model cement is pretty much useless these
days, as they have
removed nearly all of the solvent type chemicals from the product.
For styrene, butyrate, and ABS (and the plastics in HP -- at least
calculators and 95/200LX -- and grey Toshiba laptop cases), try Tenax
7R, available at well-supplied hobby shops or mailorder from Micro-Mark
(
www.micromark.com). It's a water-thin solvent. For wider cracks, you
can disolve some plastic in a small amount of solvent and flow that into
the crack.
Have you tried that product on ABS+PC blends? I've not found anything
suitable for those yet. All the solvents I've tried left the joint very
brittle. The only plastics I've found to be more difficult are nylon and
teflon (seemingly near impossible to bond back together).
